Abstract

Method for bonding a layer of thermoplastic polymer to the surface of an elastomer. A foamed elastomer having, preferably, an open-pore surface is used. The thermoplastic layer is pressed against this surface while it is heated by heat radiation, in particular laser light. The thermoplastic layer is transparent to this radiation, whereas it is absorbed by the surface of the elastomer.

Claims

exact text as granted — not AI-modified
1. A method for bonding a layer of thermoplastic polymer to the surface of an elastomer, in which the thermoplastic layer is pressed against the surface of the elastomer, while the latter is heated by heat radiation, to which the thermoplastic layer is transparent and the surface of the elastomer absorbs and which is introduced by irradiation through the thermoplastic layer characterized in that a foamed elastomer is used. 
     
     
       2. The method as claimed in  claim 1 , characterized in that the elastomer has an open-pore surface. 
     
     
       3. The method as claimed in  claim 1 , characterized in that the heat radiation is formed by laser light. 
     
     
       4. The method as claimed in  claim 1 , characterized by a thermal conductivity of the elastomer of less than 0.2 W/mK. 
     
     
       5. The method as claimed in  claim 2 , characterized in that the heat radiation is formed by laser light. 
     
     
       6. The method as claimed in  claim 2 , characterized by a thermal conductivity of the elastomer of less than 0.2 W/mK.
